The $H$ amount of thermal energy is developed by a resistor in $10\,s$ when a current of $4\,A$ is passed through it. If the current is increased to $16\,A$, the thermal energy developed by the resistor in $10\,s$ will be $........\,H$
$1$
$16$
$\frac{ 1 }{4}$
$4$
The total power dissipated in watt in the circuit shown here is ............. $W$
The ratio of heat dissipated per second through the resistance $5 \Omega$ and $10 \Omega$ in the circuit given below is: :
The two bulbs as in the above question are connected in series to a $200\, volt$ line. Then
When the power delivered by a $100\,volt$ battery is $40\,watts$ the equivalent resistance of the circuit is ........... $ohms$
Two heater wires of equal length are first connected in series and then in parallel. The ratio of heat produced in the two cases is
